SIGMA-MD Health Monitoring Relay
Type: 1 Form A (NC)
Rating: 1A @ 120V DC
All relays are electrically held and are de-energized when control power is OFF.
Failsafe:
When the failsafe option is ON the trip relay is normally energized when control power is ON and is
deenergized in a trip state. When the failsafe option is OFF the trip relay is normally deenergized when control power
is ON is energized in a trip state.
Memory:
When the memory option is ON and control power is restored after a loss of control power, the trip relay
and auxiliary fault relays are returned to the state these relays had prior to the loss of control power. The state of
the trip relay and auxiliary fault relays are maintained in memory until the relay is manually reset. When the memory
option is OFF and control power is restored after a loss of control power, the trip relay and auxiliary fault relays are
returned to their normal operating state when control power is applied.
